Computer engineering is a vast field spanning many aspects of hardware and software; thus, it is difficult
to cover it in a single book. It is also rapidly changing requiring constant updating as some aspects of it
may become obsolete. In this book, we attempt to capture the long-lasting fundamentals as well as the
new trends, directions, and developments. This book could easily fill thousands of pages. We are aware
that in this book, some areas were not given sufficient attention and some others were not covered at all.
We plan to cover these missing parts as well as more specialized topics in more detail with new books
under the computer engineering series and new editions of the current book. We believe that the areas
covered by this new edition are covered very well because they are written by specialists, recognized as
leading experts in their fields.
